You will probably not find a new one. You might find a good used one. I can reproduce them but in my opinion if you are having problems with your headlights not working you should just upgrade to my complete all in one relay kit.

I have had many requests for me to make a reproduction of this GM 10022620 isolation relay. So I am going to make them. It will take a few months. Maybe by the end of 2017. Maybe by the end of October, 2017.

My first idea is to supply them with wires and you cut off the old plugs and butt splice them to the factory wires and use adhesive shrink tube. But I'm going to look at selling them with new plugs on them. You would still need to cut your old plugs off, butt splice on the new plug, but it would be replaceable like this. With the plug it will cost more also.

They will be in a black ABS plastic box and be close to the size of the original. They will have a tab with a hole to mount them in the stock location with the original screw. The wires will exit on the bottom.
